Application filed November This invention relates to devices usedfor winding and tying reinforcements to be viincan beadjusted to different bedded in concrete pipes, or parts of pipes..A

@ne of the objects of this invention is lto facilitate a winding and tying of reinforce -mentsby automatically adjustable supports.

Another object is to provide a device that diameters.

' l 'Another object s to provide a 'device in which the multitude of pins,

i 'reinfoicingwire is to be wound,l are firmly mounted within the 'device shiftable through the rim over which wound. v .Y

Another object isto provide a Vmechanism by which the rim vsections and the multitude of pins can be adjusted and shifted to accommodate 'reinforcing wire for various diam- Vthe reinforcement Vis eters and for-'various widths by simple move-' ments of levers. v

Other objects will appear from the following description andA appended claimsas well as from theaccompanying drawing7 in whiohV f Fig. 1 is a Vin connection with levers to be operated collectively or separately by-main levers or handles, portions "being broken away to illustrate inside connections and cooperative movements o'f the severalparts.

Fig. 2 is ak fragmentary cross section on line cross section i length and diameter, the reinforcements, too, l must vary accordingly.- i

A common method of providing reinforcements is by having various eter and length with a multitude of holes into which pins are put about which the wire is Wound and tied.y To remove a finished reinforcement from such a form, the pinsV must first be withdrawn'from the form before the reinforcement can be removed in an aXialdi#l rection.`

Guides 5er@ for this @M Y sections 4:, a single vmovement by Ya simple lever is sufficient to project the pins to the outside of the rim and ont-hev other hand Ato withdraw all pins into the inside from the outside 0f the rim. A While adjustments for different diameters of pipes or pipe collars are taken care 0f b v the movements of the'rimsections and of the ypins `as far as described above, for adjusting the pins for longer or shorter pipes or for narrower collars, guide? bars 26 are provided `on the rim sections for adjustments in an axial direction. The guide bars-can be adjusted-by means of the'bolt-s 27, the rim secy tions having for this purpose. slots 28 in whichl the bolts can be shifted back and forth axially in relation to `the whole structure. Other slots 29 serve to allow the pins to pro Vject through the rim sections l in the various adjusted positions. Sleeves' 3() serve to guide the pins and to prevent a dropping of the pins from the rim sections when the pins are adjusted to a desirable diameter drawn to their-innermost positions.

The sleeves 30 are provided with enlarged ends Slfseating in countersunk holes in the plates 26.' The sleeves are hereby held with their enlarged ends between `the rim portions 4 and theV guide bars 26, and, by making the Vcoux'itersunlr holes large enough, the sleevesBO may yield suitably so that ther pins 20 mayV easily shift vthrough the sleeves in and for the different adjusted positions. With this structure the rim sections are gears 7 and 8 and the lever 14. The said pin l5 is adjusted to one of the holes`r19 in the segment bar 18V soV that the rim sections can thereby be Aheld firmly inadjusted position. The multitude of pins 204 are then merely shifted through t-he rim sec-V tions by a. simple movement of the lever25, thereby making the whole structure ready f to receive reinforcement wire over the outf side of the rim sections to be tied and wound around the pin ends 20.,

As soon as a. reinforcement'is `finished, the

pins are withdrawn into the inside by an other simple movement of the lever 25, and

lthetension of the reinforcement may be suitably released byan inward movement of therim sections from the adjusted position, so

that theV finished reinforcement can easily be removedV from the smooth pinless outside of the structure. Y

The rim sections and pins are then again set back to the previous adjusted position and one after'another reinforcement cangbe wound in the manner set forth above, Y,
